Berzelius had discovered a new element in the Falun district of Sweden and named it Thorium
after the Scandinavian God Thor.
Thorium was discovered in 1828.
The symbol for thorium for is Th.
The atomic number for thorium is 90.
The atomic mass of thorium is 232.0381
The source of the symbol is the abbriviation of the word thorium
Protons: 90
Neutrons: 90
Electrons: 142
Found in the earth’s crust in the form of a solid.
Boiling point: 4790°C
Melting point: 1750°C
Density: 11.72 g/cm3
Abundance in the earth’s crust: is relatively abundant in the earth’s crust.
Uses: source of nuclear power, strong alloys, ultraviolet photoelectric cells
Interesting facts: is a silvery white metal which maintains its luster for several months unless it is exposed to oxygen and then it eventually turns black.
